Would be nice to have other options for a guild specific location other than an airship. Perhaps a small piece of land with a tower, castle, or some other building on it. Have it operate the same way airships operate or give them some new hook point options. I know its just pretty much the same thing as an airship but just like the idea of a different feel to the guild location.

Just as an added thought...
Would be kind of cool to have some sort of side thing you could choose to do like battling another guild airship in a guild vs guild competition play. Something which could give added rewards and promote guild members doing some challenges together.
